I am currently running windows xp. Every time i turn on my computer a message appears saying the my Virus Signature File is out of date. What is this, How do i fix it.

ThanksSounds like your anti-virus files have not been updated for a while.  Try updating whichever anti-virus you are using.

If you need further assist please post details of your hardware and software in use.

I tried updating my anti virus but the message still appears. I am using AVG 9.0 paid edition not the free one.
I dont know what you mean by hardware 

This is very frustrating. AVG error messages USUALLY include a code, is the error message you posted complete?

Hardware is the bits and pieces which are bolted together to make your pc.  We don't even know if you are using a laptop, desktop, notebook etc.  When did this error message begin to appear and what, if anything, was added/deleted to/from your pc just prior to its appearance?   Does your hardware meet the minimum REQUIREMENTS to run AVG 9 (at least 512 mb ram).

Yes, we get frustrated too, mainly due to lack of information in order to do a reasonable diagnosis of the problem.  Perhaps you'd like to read this..

Oh OK sorry i did not provide more info.

I have a Philips based laptop (iQon) it has 512MB Ram, Windows XP media CENTRE sp2

I did not install anything or remove anything.

The only extra software i have on the laptop is Microsoft Office 2007, AVG 9.0, other than that is is factory default.

I tried REINSTALLING the AVG and it did not get rid of the problem either.

All help is appreciated as i need the laptop for college studies. Quote from: Me
